Using HTML Editor with Mozilla

I have tried to add 3 new pages to my site using cPanel's HTML editor. The pages I created load fine in IE. However, when you try to view those pages in Mozilla Firefox or Netscape Navigator, the pages do not load; only the source code appears.

I am using the HTML editor in IE 6.

Also, I have copied and pasted the code into Dreamweaver and used the preview feature (for Mozilla). The pages load fine in the "offline" preview. But, when I recopy the code back into cPanel, the pages still don't load properly.

Also, I have tried using both the WYSIWYG and the code editor - I still come up short in Mozilla and Netscape.
